The size of the left upper chamber of the heart is one measure of cardiovascular health. When the upper left chamber is enlarged
Ganezh [65]

Answer:

a) P [ X < 24 mm ] = 0,3015          or     P [ X < 24 mm ] =  30,15 %

b) P [ X > 32 mm ]  = 0,1251          or        P [ X > 32 mm ]  = 12,51 %

c) P [  25 < X < 30 ] = 0,4964      or     P [  25 < X < 30 ] = 49,64 %

d) z(s) = 0,84

Step-by-step explanation:

Normal Distribution    N (  μ₀  ;   σ )   is  N ( 26,5 ; 4,8 )

a) P [ X < 24 mm ] = ( X - μ₀ ) / σ

P [ X < 24 mm ] = (24 - 26,5)/ 4,8 = - 0,5208 ≈ - 0,52

P [ X < 24 mm ] = - 0,52  

And from z-table we find area for z score

P [ X < 24 mm ] = 0,3015          or     P [ X < 24 mm ] =  30,15 %

b)P [ X > 32 mm ]  =  1  - P [ X < 32 mm ]

P [ X < 32 mm ]  = ( 32 - 26,5 ) / 4,8

P [ X < 32 mm ]  = 5,5/4,8  =  1,1458 ≈ 1,15

P [ X < 32 mm ]  = 1,15

And from z-table  we get

P [ X < 32 mm ]  = 0,8749

Then:

P [ X > 32 mm ]  =  1  -  0,8749

P [ X > 32 mm ]  = 0,1251          or        P [ X > 32 mm ]  = 12,51 %

c) P [  25 < X < 30 ] = P [ X < 30 ] - P [ X < 25 ]

P [ X < 30 ]  = 30 - 26,5 / 4,8   =  0,73

From  z-table    P [ X < 30 ]  =  0,7673

P [ X < 25 ] = 25 - 26,5 / 4,8  = - 0,3125  ≈  - 0,31

From z-table  P [ X < 25 ] =  0,2709

Then

P [  25 < X < 30 ] =  0,7673 -  0,2709

P [  25 < X < 30 ] = 0,4964      or     P [  25 < X < 30 ] = 49,64 %

d) If  20 %

z- score for 20% is from z-table

z(s) = 0,84

DESPERATE FOR THE ANSWER
melisa1 [442]

Answer:

The money my sister have is $34

Step-by-step explanation:

Given as :

The two statements are as

If I give my sister 5 dollars, then we will have the same amount of money  ...A

If instead she gives me 8 dollars, then I'll have twice as much money as she has.      ......B

Let the money I have = $x

And The money my sister have = $y

Now, From statement A

x - 5 = y + 5

or, x - y = 5 + 5

or, x - y = 10          ........1

Again, From statement B

2 ×(y - 8) =  (x + 8)

2 y - 16 = x + 8  

2 y - x = 24         ........2

Now, solving Eq 1 and 2

Put the value of x from eq 1 into eq 2

2 y - (y + 10) = 24

Or, 2 y - y = 24 + 10

Or, y = 34

So, The money my sister have = y = $34

Put the value of y into eq 1

so, x - 34 = 10  

I.e x = 10 + 34

∴ x = 44

So, The money I have = x = $44

Hence, The money my sister have is $34 Answer
